During meiosis the number of chromosomes per cells is cut in half through the separation of homologous chromosome in a diploid cell. Meiosis is the process of cell division that reduces the number of chromosomes.
Meiosis.
Meiosis consists of two successive nuclear divisions. During the first division, meiosis I, each homologous pair of chromosomes is split, one chromosome to each daughter-cell. This halves the number of chromosomes.
That is called meiosis. This is mainly used in sexual reproduction. In the case of mammals, it happens within cells twice. That results in 4 sperm cells or one egg cell (with 3/4 the genetic material that would be produced discarded).
Pairing between homologous chromosomes during prophase of meiosis I and separation of these chromosomes during anaphase I result in halving the number of chromosomes in a cell.
Mitosis, on the other hand, is when you double the number of cells with the full DNA. A way to remember that one apart from meiosis is to think of a "toe." To regenerate the cells in your toe, you would use mitosis.
Also, do not confuse this with miosis. That is the narrowing of the pupils in the eye. Mydriasis (dilation) is its opposite.
It is called meiosis.

The "X" chromosome . . . I believe it is number 23 . . .
Total number of chromosomes remain same in same species of organism through meiosis process. In meiosis process the number of chromosomes are reduced to half as a result in gametes only one set of chromosomes will be present. In this process chromosomes are same.....
Meiosis.
The cellular chromosome number is reduced from 2N to 1N.
Short Answer: the [it appears] one, extra, cellular process that only Meiotic Cells possess is termed "Chromosome Reduction"; we have seen (elsewhere) that this process results in the reduction of Chromosome Number from the mitotic {somatic} 2N to the Meiotic {gametic} 1N.

gene,chromosome THEN nucleus :) HOPE YOU DO WELL !!

there is no reduction of chromosome number.
